.'B'e it known that I, Roanne?. Ross, ofethlehom', in the county ofNorthampton, and Stilte ot Pennsyl- Ivnnie, have invented c new andimproved Basin Water-Oock-; and I-do hereby declare that tbe followingis s Toll, clear-fond exact description thereof, which will enableothers skilled in the art vto make-ond use the seme, reference being hed to the accompanying drawing, forming port of this speciceticn.

This invention relates to the manner in which the cock is' packed, endit consists in orrengibg a dropvalve with an elastic fece, which isoperated by e screw, whereby-ell lechage is prevented, as willbehrenefter described.4

The drawing represents a. vertical longitudinal section of the cock,showing the general errnngement'of l tbe parts 'of which it is composed,and the mimnerin which they are combined.

A representsthe tnbecr 'body' of the cock. B isthe hollow chamber, whichscrews lon to the tube *G -is the cap of the cock, 'which screws intothe'pcrt B'. 4D i's' the drop-valve, which is placed in the chamberloose when the cap is olf. This valve has c stem, which rnns np into theccp, es eeenin the drawing. The lower portion of D forms a recess, intowhich is'ploced rubber or someothersnitable elastic packing, which ismsrked'E. F is the spout or delivery-tube of the cock, which -islscrewed fest into the chamber B, and by whichlthe chamber is' turned esby n lever `o'n the tube Af. 0n ther'bot-tcm en d of the chamber B thereis a'supportingmut, G, which moves with the chamber. 'As represented inthe drawing, the'top ofthe water-tube A is closedagainst thcpaclringE. ABy turning the cbiember B, with the' discharge-pipe or spout F, so as tonnscrew it, the packing of -the vblve E will be raised from the endofthe tube A, and water will flow therefrom into the chamber E, and bedisoherged bythespoutF. f

As-these basin-cocks have heretoforeben made, the joint on theAtop ofthe tube has' been formed of metallic srfsces','and, in conseguencqithas been` extremely diicult to prevent lechage.v To remedy 'thisdicnlty. is the'object of-the presentimprove'ment.

. f'Havngthus described my invention, I claim as new, and desire tosecure by-Letters -Pptentf- Il. The cap C, when made hollow for thereception of -the stem of the valve D, sid valve `having its sent uponthe tube A, within the' chamber B, usher-ein described, for the purposespecified.

2. The loose valve D, in Vtlxe'tighi cop C, fitting into the upper endof the chamber B, the packing', Eroi" I said valve resting upon theupper eridof the stem A, when the water is shut ofl by t'nhrnng downsaid chamber,

and-lifted above the endof thev stem- A when the wntcr is turned on, bytnrningnp seid chamber, es herein shown and described..

The nb'bvesp'ecificction of my invention signed by me, this 19th doy ofJune, 1867. v ROBERT P. ROSS.
